Carbon disulfide can be prepared from coke (an impure form of carbon) and elemental sulfur:
4C(s) + S8(s) --> 4 CS2(l) ΔH°= +358.8 kJ

(b) Calculate the heat absorbed in the reaction of 197 g of carbon with an excess of sulfur. (c) If the heat absorbed in the reaction was 415 kJ, how much CS2 was produced?

Can someone walk me through parts b + c?

you can use the enthalpy as a conversion factor. I hope this helps.

Like the above post mentions, a good way to think about is in stoichiometric terms. Just make sure each individual conversion makes sense and relates to the amount of moles in the chemical equation provided.
